Description
Die Erfindung betrifft eine explosionsgeschützte, stoßsichere Handleuchte mit einem aus transparentem, biegsamem Kunststoff bestehenden, an seinen Enden durch gepolsterte Abschlußhauben aus gummielastischem Material verschlossenem Schutzrohr, in dessen Innerem zwei eingesetzte gummielastische kreisförmige Tragplatten je ein Ende von einer oder mehr Leuchtstoffröhren halten.The invention relates to an explosion-proof, shock-proof hand lamp with a transparent, made of flexible plastic, at its ends by padded end caps Rubber-elastic material sealed protective tube, inside which two rubber-elastic elements are inserted circular support plates each hold one end of one or more fluorescent tubes.
Die dadurch angestrebte Abdichtung hat man· noch dadurch zu verbessern gesucht, daß man dieThe attempted sealing has been sought to improve by the fact that the
Enden der Lampe in elastischen mit Topfrändern versehenen Tragteilen halterte. Diese und andere Vorschläge stellen zwar wirksame Maßnahmen zur Verhinderung jeglichen Gas- und Flüssigkeitsdurchganges zwischen dem Innern der Leuchte und dem Auüenraium und damit zur Vermeidung von Explosionen in explosionsgefährdeten Räumen dar, sie sind aber nicht dazu angetan, hinsichtlich einer wirklichen Stoßsicherung der Leuchte befriedigende Resultate zu erzielen.The ends of the lamp were held in elastic support parts provided with pot edges. These and others Proposals do provide effective measures to prevent any gas and liquid passage between the interior of the luminaire and the outside area and thus to avoid explosions in potentially explosive areas, but they are not suitable for a real shock protection of the luminaire to achieve satisfactory results.
Dieser ebenso wichtigen Anforderung an eine betriebssichere Handleuchte gleichzeitig zu genügen, ist Zweck der Erfindung. Nach der Erfindung sind die Tragplatten auf ihren einander abgekehrten Seiten mit Topfrändern versehen, deren Länge mindestens gleich dem Radius der Tragplatte ist, dienen ebenso lange, entgegengerichtete Ränder der Abschlußhauben so gegenüberstehen, daß zwischen diesen sich gegenüberstehenden Rändern über deren ίο ganze Länge das Schutzrohr eingeklemmt ist.To meet this equally important requirement for a reliable hand lamp at the same time, is the purpose of the invention. According to the invention, the support plates are on their sides facing away from one another provided with pot edges, the length of which is at least equal to the radius of the support plate, are used just as long, opposite edges of the end hoods face so that between them opposing edges over the entire length of which the protective tube is clamped.
Dadurch wird eine erhebliche Stoßsicherheit sowohl in axialer als auch in radialer Richtung (bezogen auf den Lampenkörper) erreicht. Letztere kann noch dadurch erhöht werden, daß die Ränder der Abschlußhauben an ihrer Außenseite im Querschnitt hakenförmige Polsterringe ""aus gummielastischem Material tragen, welche Luftpolsterringe derart übergreifen, daß beim Zusammenpressen dieser Polsterringe die Luft aus Umfangsringao spalten gehemmt austritt.As a result, considerable shock resistance is achieved both in the axial and in the radial direction (related to on the lamp body). The latter can be increased by the fact that the margins the end cap on its outside in cross-section hook-shaped cushion rings "" made of rubber-elastic Wear material which overlap air cushion rings in such a way that when pressed together these cushion rings the air escapes from circumferential ringao split inhibited.

Fig. 5 zeigt einen Längsschnitt durch eine elektrische Durchführung dlurch eine der Tragplatten in vergrößertem Maßstab.FIG. 5 shows a longitudinal section through an electrical bushing through one of the support plates in FIG enlarged scale.
Die Leuchte gemäß den Fig. 1 bis 3 besteht aus einem zylindrischen Rohr 1 aus transparentem, biegsamem Kunststoff, auf dessen Enden je eine mit Polsterringen 2 versehene Hauben 3 bzw. 4 aus elastisch nachgiebigem Werkstoff flüssigkeits- und gasdicht aufgesteckt oder aufgeschraubt sind.The lamp according to FIGS. 1 to 3 consists of a cylindrical tube 1 made of transparent, flexible plastic, on each of the ends one with Padding rings 2 provided hoods 3 and 4 made of elastically resilient material liquid and are plugged in or screwed on in a gastight manner.
Im Innern des Rohres sind zwei Tragplatten 5 bzw. 6 aus ebenfalls elastisch nachgiebigem Werkstoff vorgesehen, die zusammen mit zwei Fluoreszenzleuchtröhren 7, einem Druckkontaktstarter 8, den notwendigen Verbindungsdrähten 9 und einem Lichtreflexionsschirm 10 eine stabile Leuchteinheit bilden.Inside the tube are two support plates 5 and 6, which are also made of elastically flexible material provided, which together with two fluorescent tubes 7, a pressure contact starter 8, the necessary connecting wires 9 and a light reflection screen 10 a stable lighting unit form.
Die Enden der Leuchtröhren 7 sind in Ausnehmungen auf den Stirnseiten der Tragplatten 5, 6 eingesteckt, während die Anschlußstifte und die notwendigen Verbindungsleitungen 9 -durch die Tragplatten durchgeführt und auf deren äußeren Seiten gemäß dem Schaltbild nach Fig. 4 unter sich sowie mit dem Startschalter 8 und den beiden Adern des Stromzuführungskabels 20 elektrisch verbunden sind.The ends of the fluorescent tubes 7 are in recesses on the end faces of the support plates 5, 6 plugged in while the connector pins and the necessary Connecting lines 9 - passed through the support plates and on their outer sides according to the circuit diagram of FIG. 4 among themselves and with the start switch 8 and the two wires of the Power supply cable 20 are electrically connected.
Das Stromanschlußkabel 20 ist luft- und gasdicht in eine Tülle der Schutzhaube 4 eingeführt, beispielsweise eingeschraubt und weist (Fig. 4) ein Vorschaltgerät 12, bestehend aus einer Drosselspule I2a und einem Kondensator I26 auf. Das Vorschaltgerät befindet sich in einer aus zwei Teilen 11 und 110 bestehenden Schutzhülle (Fig. 1).The power connection cable 20 is inserted air-tight and gas-tight into a grommet of the protective hood 4, for example screwed in, and has (FIG. 4) a ballast 12 consisting of a choke coil I2 a and a capacitor I2 6 . The ballast is located in a protective cover consisting of two parts 11 and 11 0 (FIG. 1).
Der Starter 8, hier ein Drucktastenschalter, ist zwischen der Schutzhaube 3 und der benachbarten Tragplatte 5 derart eingebaut, daß ein Druckknopf 81 durch Drücken auf das dünnerwandige Zentrum 31 der Schutzhaubenstirnfläche betätigt werden kann, wodurch die Röhren gezündet werden.The starter 8, here a push button switch, is between the protective hood 3 and the neighboring one Support plate 5 installed so that a push button 81 by pressing on the thinner-walled center 31 of the protective hood face can be actuated, whereby the tubes are ignited.
Es könnte auch statt dieses Drucktastenstarters ein Glimmstarter vorgesehen· sein.A glow starter could also be provided instead of this pushbutton starter.
Die Polsterringe 2 gemäß Fig. 2 zeichnen sich durch eine sehr wirksame Dämpfung von mechanischen Stößen aus, indem sie derart profiliert sind, daß sie, im Querschnitt gesehen, hakenförmig Luftpolsterringe übergreifen, so daß beim Zusammenpressen dieser Polsterringe die Luft aus den Umfangsringspalten gehemmt austreten kann.The cushion rings 2 according to FIG. 2 are characterized by a very effective damping of mechanical Impact by being profiled in such a way that, viewed in cross section, they are hook-shaped air-cushion rings overlap, so that when these cushion rings are pressed together, the air from the circumferential ring gaps can escape inhibited.
Auf der Schutzhaube 4 ist gemäß Fig. 1 ein Klemmring 14 aufgespannt, an welchem mittels eines Kugelgelenkes 15 ein Handgriff 16 angelenkt ist, wobei die Gelenkverbindung durch Anziehen der Flügelschraube 17 festgestellt werden kann.On the protective hood 4, a clamping ring 14 is clamped according to FIG. 1, on which means of a ball joint 15, a handle 16 is articulated is, wherein the articulation can be determined by tightening the wing screw 17.
Gemäß Fig. 5 ist vorgesehen, daß die Zuführungsleitungen durch die Tragplatten 5 bzw. 6 trennbar ausgebildet sind.According to FIG. 5 it is provided that the supply lines can be separated by the support plates 5 and 6, respectively are trained.
So sind beispielsweise auf die Anscblußkontaktstifte 91 der Leuchtröhre 7 Klemmhülsen 92 aufgeschoben, in deren Innerem je ein Silberkontaktbolzen 93 durch eine Schraubenfeder 94 aus elektrisch gut leitendem Material gegen das Ende des betreffenden Kontaktstiftes· 91 gedrückt wird.For example, on the connector pins 91 of the fluorescent tube 7 clamping sleeves 92 pushed on, inside each of which a silver contact bolt 93 by a coil spring 94 made of electrically good conductive material against the end of the respective contact pin · 91 is pressed.
An ein aus dem hinteren Ende der Klemmhülse 92 herausragendes Federdrahtstücfc 92,,, welches aus einem Ende des Federdrahtes besteht, ist eine Seele des Zuleitungskabels 20 bzw. des Startschalters bzw. ein Anschlußstift eines Glimmstarters oder ein Verbindungsdraht 9 angeschlossen.To a spring wire piece 92, which protrudes from the rear end of the clamping sleeve 92, consists of one end of the spring wire, is a core of the supply cable 20 or the start switch or a connection pin of a glow starter or a connecting wire 9 is connected.
Diese Durchführungen sichern bei leichter Demontierbarkeit zum Ausbau einen dauernden, nicht funkenerzeugenden elektrischen Kontakt zwischen den zu verbindenden Organen, weil die Federn 92 den Silberbolzen 93 immer gegen den Kontaktstift 91 pressen.These bushings secure with easy dismantling permanent, non-sparking electrical contact between the organs to be connected because the springs 92 keep the silver bolts 93 against the contact pin 91 press.
